Patented Sept. 3, 1935 UNITED STATES PATENT OFFICE '7 Claims.

This invention relates to containers, including barrels, andparticularly to those made from thin sheet material, like ply wood,fiber sheets, etc.

When making a container body of sheet mate- 5 rial, one or morelongitudinal joints are necessary,

where parts of the sheet come together. These joints are sometimes madeas butt joints, having a thin piece or strip of some kind, as sheetmetal, lapped over the abutting parts, and are securely fastened theretoby clinched rivets or staples. Some longitudinal joints are formed bylapping the adjoining parts and securely fastening these lapped partstogether by clinched rivets or staples, thus eliminating the necessityof using an extra overlapping strip, as with a full length, butt joint.But the ends of such a longitudinal, lapped joint form in the case of abarrel, long, triangular openings, at the barrel heads, permitting agranulated or powdered barrel content to sift through.

One of the objects of my invention is to provide a construction ofbarrel or container made of sheet material, wherein the longitudinaljoint in the body of the. barrel or container is mainly of lapformation, terminating at its ends in transformed butt formations at theperipheral zones of the barrel headers, so as to there present acontinuous thickness of material next to the periphery of each barrel orcontainer head, and thus avoid any triangular opening at the jointportion adjacent the barrel heads, which would otherwise be formedwithout resorting to such transformation into a butt portion of joints.

Another object in connection with the transformation of a portion of thelap joint to a butt joint, at the heads, is to strengthen the head endsof the barrel by having a continuity of contact made possible at thebutt portions of the joints, between the outside hoop and the twoliners, on the opposite sides of each header, which are firmly attached,with the body sheet, to the outside hoop.

A further object of my invention is to provide a sift-proof seal at thechange of formation of lap joint to butt joint, by cementing over thecracks, paper or other thin material, suitable for the purpose, or bythe formation of a cement film across the cracks.

Another object is to provide with each header disc, an overlapping,sealing sheet, within the barrel and next to each disc, to make thejoint sift-proof around the periphery of the disc.

A further'object is to strengthen the thin sheet body of a barrel, atone or more zones, between theheaders, by means of a stifiening hoop putnext to the inside of the barrel body, to serve as an arch support tothe curved thin wall of the barrel, to strengthen the same against anoutside impact.

And a further object is to stiffen and strength- 5 en the inside hoop byproviding an outside hoop, opposite the inside hoop, fastening togetherthe two hoops, with the barrel body between, by some clinched fasteningmeans, as rivets, nails or staples, forced therethrough.

With these and other objects, which will hereinafter appear, myinvention resides in certain construction, one embodiment of which isillustrated in the drawing, and. is hereinafter described. Its featuresare explained, and what I claim is set forth.

In the drawing,

Figure 1 is a perspective view of a barrel or container embodying myinvention. Parts are broken away to illustrate the construction.

Figure 2 is an inside view of a joint fragment of the barrel shown inFigure 1.

Figure 3 is an inside view of the same joint structure shown in Figure2, but exclusive of the header and liners, showing how the lap jointmerges into a butt joint, by having a notch in the corner of the insidelap portion, of the longitudinal joint.

Figure 4 shows a similar joint structure to that shown in Figure 3, buthas the notch in the corner of the outside lap portion, of thelongitudinal joint.

Figure 5 shows the same joint structure illustrated in Figure 4, exceptit is here shown reversed in position to correspond to the lower part 5of the longitudinal joint, shown in Figure 1.

Figure 6 is a fragmental mid-section of a barrel, showing the walldistorted and separated from the outer hoop, by an impacting object, inthe absence of an arch formed by an inner hoop.

Figure '7 illustrates a section of barrel wall with an inside hoopserving as a supporting arch.

In the figures, the bent sheet [0, forming the barrel or container bodymay be of any material, including ply-wood, which may be of any numberof plies, and is shown in the drawing to be of three-ply wood, having alongitudinal joint I l with a long portion [2, which is shown to have anouter part I3, overlapping an inner part M. The parts [3 and I4, beingintegral with the body sheet H), are held overlapped together, by clinchfasteners l5, which may be rivets, staples or nails. The upper corner,of the joint part I4, is notched at l6, and the corner 11, of the outerpart I3, is bent into the notch l6, so that it presses tight 5&

against the horizontal edge l8, of the notch 16, and so that the longedge 59, of the part [3, butts against the vertical edge Zil, of thenotch 16. The butt joint 2!, so formed, is in the zone of the plane, ofthe header 22, seated upon an inner liner 23, and has a paper disc seal25-, overlapping the header 22, sufiiciently to lay next to theperiphery of the header 22, and to extend up behind the outer liner 25.The horizontal edge I 8, of the notch It, is preferably positioned tocome next to, and to be below the inner liner 23. In the same zone withthe liners 23 and 25, and the header 22, is an outside hoop 26, wideenough to be properly engaged by clinched fastening means 2?, bindingtogether. the hoop 26, the outer liner 25, the upstanding part of thepaper seal 24 and the body sheet NJ, and also the inner liner 23, withthe body sheet It and the hoop 26.

The lower end of the longitudinal joint H is shown to have atransformation from a lapped joint portion to a butt joint portion,wherein the notch 28 is made in the lower corner, of the outside jointpart I3, and the lower corner of the inside joint part I4 is bentoutward, so that it bears against the horizontal edge 29, of the notch28, and so that the long edge 30, of the inner part 14, butts againstthe vertical edge 3 l of the notch 28. The butt joint 32, so formed, isin the zone of the plane of the lower header 33, associated with liners23 and 25, outside hoop 26, and paper seal 24, the same as with header22 at the top of the barrel. It will be noticed in Figure 1, that thehorizontal edge 29, of the notch 28, is on top of the lower, of thehoops 26.

Referring now to the stiffening and strengthening means fixed to thebarrel body it, midway of its length, there are shown two hoops, onemarked '34, on the inside, and one marked 35, on the outside, withclinched fasteners 36, binding the hoops and the body wall It together.A suitable paper patch, or film of glue or cement covers the cracksabout the butt joint transformations and the joints.

In Figurefi is shown a wall section fragment marked Ill with an outerhoop fragment marked 35*, with two spaced clinched rivets marked 36 inbetween which, but to one side of the hoop 35 is an impacting object,marked 37, shown to have forced the wall section Ill inward, from thehoop 35%, between the rivets 36 in the absence of an inner hoop, toprevent this distortion.

In Figure 7- is shown a wall section fragment marked Ill with an innerhoop fragment marked 34*, and two spaced clinched rivets se in betweenwhich, but to one side of the hoop 36 is an impacting object, marked 31shown to have been resisted and held'against distorting the wall sectionIll by the arched action of the inner hoop 34 Where an outside and aninside hoop are used in the same zone, as 35 and 36 respectively, shownin Figure l, with clinched fasteningmeans 36, therethrough, the hoop 35,while in itself will resist anoutside impact, also will strengthen theinner arching hoop 34, against an inward distortion of the barrel wallbody lli.

While I have shown and described a barrel or container body made of asingle sheet of material, obviously the body can be made upcircumferentially of a plurality of sheets, having a plu- .or bothends,.or at any intermediate point in the zone of an interior orexterior hoop. The transformed butt formation affords a joint portion ofcontinuously uniform thickness, with the other parts of the sheet barrelwall contacted by hoops, liners or headers. Any crack co-incident withthe formation of such a butt portion, of joint can be easily sealed overby cementing over the-crack a piece of suitable paper, or by coveringthe crack with a film of cement or glue, as above indicated.

The paper sealing disc 2 1, used to seal the joint at the periphery ofthe header 22, is enough larger in diameter than the header 22, to bebrought up behind the upper liner 25, which, when secured in place byclinched fasteners, binds the peripheral overlap of the paper disc 25 tothe barrel body 63.

Relative to the inside hoop 35, its resistance, serving as an arch,-tostiffen and strengthen the body wall it, against distortion by animpacting object 3?, is illustrated in Figure 7, while in Figure 6, theimpacting object 37, is represented as 7 having partly pushed in thewall section it, at a portion which is between the fasteners 36%, andaway from the outside hoop section 35 Inasmuch as changes in the oneembodiment of my invention herein illustrated and described. can be madewithout departing from the spirit and scope thereof, I wish to includeall forms and changes which come within the purview of. the

following claims.
